Spin-wave study of entanglement and Rényi entropy for coplanar and collinear magnetic orders in two-dimensional quantum Heisenberg antiferromagnets
Dag-Vidar Bauer, J. O. Fjærestad
We use modified linear spin-wave theory (MLSWT) to study ground-state entanglement for a length- line subsystem in square- and triangular-lattice quantum Heisenberg…

Unified explanation of the Kadowaki-Woods ratio in strongly correlated materials
A. C. Jacko, J. O. Fjaerestad, B. J. Powell
Discoveries of ratios whose values are constant within broad classes of materials have led to many deep physical insights. The Kadowaki-Woods ratio (KWR) compares the temperature d…

Broken time-reversal symmetry in strongly correlated ladder structures
U. Schollwoeck, Sudip Chakravarty, J. O. Fjaerestad +2
We provide, for the first time, in a doped strongly correlated system (two-leg ladder), a controlled theoretical demonstration of the existence of a state in which long-range order…
